Purpose We examined indices of narrative microstructure as metrics of language development and impairment in Arabic-speaking children. We examined their age sensitivity, correlations with standardized measures, and ability to differentiate children with average language and language impairment. Method We collected story narratives from 177 children (54.2% boys) between 3.08 and 10.92 years old ( M = 6.25, SD = 1.67) divided into six age bands. Each child also received standardized measures of spoken language (Receptive and Expressive Vocabulary, Sentence Imitation, and Pseudoword Repetition). Several narrative indices of microstructure were examined in each age band. Children were divided into (suspected) developmental language disorder and typical language groups using the standardized test scores and compared on the narrative indicators. Sensitivity and specificity of the narrative indicators that showed group differences were calculated. Results The measures that showed age sensitivity included subject omission error rate, number of object clitics, correct use of subject–verb agreement, and mean length of utterance in words. The developmental language disorder group scored higher on subject omission errors (Cohen's d = 0.55) and lower on correct use of subject–verb agreement (Cohen's d = 0.48) than the typical language group. The threshold for impaired performance with the highest combination of specificity and sensitivity was 35th percentile. Conclusions Several indices of narrative microstructure appear to be valid metrics for documenting language development in children acquiring Gulf Arabic. Subject omission errors and correct use of subject–verb agreement differentiate children with typical and atypical levels of language development.

Purpose This study investigated the production of tense and subject–verb agreement in Palestinian Arabic–speaking children with developmental language disorder (DLD) in comparison to their typically developing (TD) peers in terms of (a) performance accuracy and (b) error patterns. Method Participants were 14 children with DLD aged 4;0–7;10 and 32 TD children aged 3;0–8;0 matched on nonverbal abilities. Children were asked to complete a picture-based verb elicitation task. The task was designed to measure the production accuracy of tense and subject–verb agreement inflections in Arabic. Results The DLD group scored significantly lower than the TD group on the verb elicitation task. The DLD group was significantly less accurate than the TD group in marking tense, specifically present tense. They were also less accurate in marking agreement in general, with specific difficulty in using feminine verb forms. The DLD and TD groups differed in their tense error patterns, but not in agreement error patterns. Conclusions The acquisition of verb morphology in Palestinian Arabic–speaking children with DLD appears to be delayed and possibly different from their TD peers. The DLD group found the production of marked verb forms more challenging than less marked ones. These results are discussed in light of the structural characteristics of Arabic. Future studies would need to include larger sample sizes; investigate other aspects of verb morphology, including both production and comprehension; include other language domains; and consider longitudinal designs to provide more in-depth knowledge of Arabic language acquisition.

Purpose The aim of the study was to evaluate the efficacy of a theoretically motivated explicit intervention approach to improve regular past tense marking for early school-age children with developmental language disorder (DLD). Method Twenty-one children with DLD (ages 5;9–6;9 [years;months]) were included in a crossover randomized controlled trial (intervention, n = 10; waiting control, n = 11). Intervention included once-weekly sessions over 10 weeks using the SHAPE CODING system, in combination with a systematic cueing hierarchy to teach past tense marking. Once the first group completed intervention, the waiting control group crossed over to the intervention condition. The primary outcome was criterion-referenced measures of past tense marking with standardized measures of expressive and receptive grammar as the secondary outcome. Ancillary analyses on extension and behavioral control measures of morphosyntax were also conducted. Results There was a significant Time × Group interaction ( p < .001) with a significant difference in pre–post intervention improvement in favor of the intervention group ( p < .001, d = 3.03). Further analysis once both groups had received the intervention revealed no improvement for either group on past tense production during the 5-week pre-intervention period, significant improvement pre–post intervention ( p < . 001, d = 1.22), with gains maintained for 5 weeks postintervention. No significant differences were found on pre- to postintervention standardized measures of grammar, or on extension or control measures. Conclusions The efficacy of the theoretically motivated explicit grammar intervention was demonstrated. Results contribute to the evidence base supporting this intervention to improve past tense production in early school-age children with DLD, suggesting it is a viable option for clinicians to select when treating morphosyntactic difficulties for this population.

Purpose We examined four measures of lexical diversity in the narratives of children with typical language development (TLD) and developmental language disorder (DLD) that comprised the normative sample of the Edmonton Narrative Norms Instrument (Schneider et al., 2005). The purpose was to document the properties of each measure with respect to variations in utterance and sample length, developmental trends, and group differences. Method The sample consisted of 377 picture-elicited, story generation transcripts from children with TLD ( n = 300) and DLD ( n = 77) aged 4–9 years. We extracted the moving-average type–token ratio (MATTR) and the number of different words from the full sample, from samples equated for the number of utterances, and from samples equated for the total number of words. Results MATTR was the only measure to show no relationships to utterance or sample length. All measures showed significant positive growth with age and significant groupwise differences between children with TLD and DLD. However, the magnitude of age effects and differentiation between groups varied considerably across measures. Across measures, there were significant differences in the number of children with DLD who were identified with low lexical diversity relative to their same-age peers in the TLD group. Conclusion The results of this study support the view that different measures of lexical diversity may be appropriate for different clinical purposes. It is important for clinicians to understand how measures of lexical diversity function in order to make educated choices among measures and ensure appropriate interpretation.

Do So

Our visual environment is highly predictable in terms of where and in which locations objects can be found. Based on visual experience, children extract rules about visual scene configurations, allowing them to generate scene knowledge. Similarly, children extract the linguistic rules from relatively predictable linguistic contexts. It has been proposed that the capacity of extracting rules from both domains might share some underlying cognitive mechanisms. In the present study, we investigated the link between language and scene knowledge development. To do so, we assessed whether preschool children (age range = 5;4–6;6) with Developmental Language Disorder (DLD), who present several difficulties in the linguistic domain, are equally attracted to object-scene inconsistencies in a visual free-viewing task in comparison with age-matched children with Typical Language Development (TLD). All children explored visual scenes containing semantic (e.g., soap on a breakfast table), syntactic (e.g., bread on the chair back), or both inconsistencies (e.g., soap on the chair back). Since scene knowledge interacts with image properties (i.e., saliency) to guide gaze allocation during visual exploration from the early stages of development, we also included the objects’ saliency rank in the analysis. The results showed that children with DLD were less attracted to semantic and syntactic inconsistencies than children with TLD. In addition, saliency modulated syntactic effect only in the group of children with TLD. Our findings indicate that children with DLD do not activate scene knowledge to guide visual attention as efficiently as children with TLD, especially at the syntactic level, suggesting a link between scene knowledge and language development.

AbstractThe aim of this study was to assess the criterion validity of a new screening instrument, the Early Language Scale (ELS), for the identification of young children at risk for developmental language disorder (DLD), and to determine optimal age-adjusted cut-off scores. We recruited a community-based sample of 265 children aged 1 to 6 years of age. Parents of these children responded on the ELS, a 26-item “yes-no” questionnaire. The children were assessed with extended language tests (language comprehension, word production, sentence production, communication). A composite score out of these tests (two tests below – 1 SD or one below − 1.5 SD) was used as reference standard. We assessed the validity of the ELS, measured by sensitivity, specificity, predictive values, and AUC. The optimal sensitivity/specificity age-dependent cut-off ELS score was at 15th percentile. Sensitivity and specificity were 0.62 and 0.93, respectively. Positive predictive value was moderate (0.53), negative predictive value was high (0.95), the positive likelihood ratio was 9.16, and negative likelihood ratio was 0.41. The area under the ROC curve was 0.88. The items covered the increasing language development for the ages from 1 to 6.Conclusion: The ELS is a valid instrument to identify children with DLD covering an age range of 1 to 6 years in community-based settings. What is Known:• Early identification and treatment of developmental language disorders can reduce negative effects on children’s emotional functioning, academic success, and social relationships.• Short, validated language screening instruments that cover the full age range of early childhood language development lack.What is New:• The 26-item Early Language Scale (ELS) is a valid instrument to identify children at risk for developmental language disorder in well-child care and early educational settings among Dutch children aged 1–6 years.

Referential Expressions

This research analyzed adequacy of referential expressions in the narratives of bilingual and monolingual children with Developmental Language Disorder (DLD) and typical language development (TLD), aiming to shed light on the relative contribution of morpho-syntactic, discourse-pragmatic, and semantic constraints. Narratives were collected from 51 children using a storytelling procedure ( MAIN – Multilingual Assessment Instrument for Narratives). Participants were 18 bilingual Russian-Hebrew preschool children (8 with DLD), 17 monolingual Russian speakers (9 with DLD), and 16 monolingual Hebrew speakers (5 with DLD) aged 5;6–6;7. Referential expressions were coded for form (noun phrase [NP] or pronoun) and character function (Introduction or Maintenance). Analyses addressed the effects of proficiency group (TLD/DLD), language group (bilingual/monolingual), and language (Russian/Hebrew) on inadequate pronoun use and definiteness. Results demonstrated that children in all groups introduced characters using NPs. Children with DLD used more morpho-syntactically inadequate pronouns, such as incorrect gender, while both children with DLD and those with TLD used similar numbers of discourse-pragmatically inadequate pronouns. Bilinguals used more morpho-syntactically inadequate pronouns than monolinguals. In Hebrew, bilingual children with DLD omitted definite articles for character Maintenance more frequently than bilingual children with TLD and monolingual Hebrew-speaking children with DLD. Wrong gender assignment indicates that children with DLD have difficulties with morpho-syntactic constraints. Omission of definite articles for character Maintenance indicates a possibility of both morpho-syntactic and semantic difficulties that bilingual children with DLD acquiring Hebrew face. The results offer insight into the nature of the difficulty observed in bilingual children with DLD in using referential expressions.
